From the looks of it, so far your team is quite solid. A good mix of offensive and defensive options. I don't think there are any need for changes right now. The spinarak that you swapped, when it evolves could be quite a menace. IMO, the strongest mons on your team so far, is Combusken and Roselia , they can really help you get through Reborn. If you have a male Espurr, then it could help you with it's ability to set up priority screens. If not, then espurr is still a splendid Sp. Attacker early game
Notable mons that you could get (as mentioned by VividGrey) are Mightyena with Intimidate to come in clutch against strong physical mons and Technician Kricketune wrecks early game but falls off quite quickly, so beware. Trubbish setting up Toxic Spikes could also help you wear down your enemy's mons. Also, I highly recommend that you get a Woobat in the Opal Ward by following the train tracks to the east of Peridot and stepping on the dark spots on the ground. You could use Simple + Calm Mind to sweep most of the fights.
But, ultimately the decision is on you, you can get through Reborn with only mons that you like just fine with enough prep. Even 'bad' mons can shine in Reborn, if used correctly.
Hope it helps!
P. S. Speed Boost Torchic/Combusken/Blaziken is amazing
